Application January 28, 1938, Serial No. 187,423 In Germany February 11,1937 l Claims.

present available for this' purpose are so conl structed that adjustmentthereof is limited, and such adjustment asis possible in such devices isof a coarse nature. It is,.therefore, an object of this invention toprovide a device of this kind which is very simple in construction sothat when once adjusted it Will not get out of adjustment readily.

Another object of this invention is to provide a toe piece for a ski,which is simple in construction and at the same time so constructed thatany desired adjustment thereof may be made,A and such adjustment will bemaintained at all times even though certain portion-.sor parts of thedevice become loosened due to expansion and contraction of the woodforming the ski.

A further object of this invention is to pro-vide an adjustable toe.piece for a ski which admits of the separate adjustment of each sidethereof, andwherein the adjustment of the side pieces 3Q may be made atany time without injury to the surface of the ski and without affectingthe character ofany subsequent adjustment which may be desirable.

With the foregoing and other objects in view,

the invention will -be more fully described hereinafter, and will bemore particularly pointed out in the claims appended hereto.

Referring to the drawing, the numeral I0 dese: ignates generally a skiwhich may vbeconstructed of any suitable material such as laminated wood5 ,s or the like. A toe piece comprising two members II and I2 issecured to thev upper surface of the ski I0 at a suitable point alongthe length thereof.

The toe piece member II .comprises a bottom 10" plate I3 which isprovided with .an upstanding flange I4 at its outer edge which hashorizontal andsubstantial Vertical slots I5 and I6, respectively,therein throughwhichstraps or like fas? tening means are adapted toengage.. Instead of 15;. slots I6, projections o f various kindsmay besubstituted in the known mannen for hooking on, straps, springs, etc.,as shown inFigures 6 and 7. Figure 6 shows one form of projections` 6I)and 6I bent out of the side plates to hook on go the end of straps orthe like, and Figure 7 shows another type of projection 63 riveted on tothe' side plate. The upstanding flange I4 is adaptedv toengage againstoneside of a shoe.` The bottom plate I3 is provided at itsforwardend'with g5 a downwardly extending` flange I1 and at its rear edge with asimilar flange I8, so that the Ibottom plate I 3 is maintained inupwardly spaced relationto the adjacent face of the ski IIJ.

A pair of locking or holding platesV I9 and 30 20 are disposed in thespace 2|` between the under face of the bottom plate I3 andthe top ofthe ski IIl, the plate I9 being disposed with its outer end adjacent thefront ange I1, and the plate 2l) being disposed with its outer end 35adjacent the rear flange I8. The confronting or inner -ends of theplates I9 and 2D are preferably spaced apart, although if desired theymay be disposed closely adjacent one another a distance sufficient topermit adjustment of one plate rela- 40 tive to the other. n

The plate I9 is provided on its upper side with serrations or teeth 22and 23, the serrations or' teeth 22` being positioned' across the frontpor# tion of the plate I9, and the serrations or teeth 23 being disposedacross the rear portion of the plate I9. The under side of the bottomlplate I3 is provided with complementary serrations or teeth 24 and 25which are adapted to engage with the serrations or teeth 22 and 23,respec 5 6 tively, so as to hold the front portion of the plate I3against lateral movement.

A screw or'fastening member 26 which is pro-k vided with ahead 21engages through van' clon-'- gated slot 28 provided in the forwardvportion 55 of the bottom plate I3, the head 21 of the screw 26 beingcountersunk in the slot 28 so that the upper surface of the plate I3will be smooth. The shank of the screw 26 passes through a circular hole29 provided in the front plate I9, so that the plate I9 may be pivotallyadjusted on the ski I0, but is held against lateral and longitudinalmovement thereon.

The rear plate 20 is also provided on the upper surface thereof withserrations or teeth 30 and 3I similar to the serrations or teeth 22 and23 of the front plate I9, and in like manner the under side of thebottom plate I3 is provided with serrations or teeth 32 and 33engageable with the serrations or teeth 3U and 3|, respectively.

A rear screw or fastening member 34 engages through an elongated slot 35provided in the bottom plate I3 and then passes through a hole 36 in theplate 2U.

'Ihe plates I9 and 20 may be positioned in recesses provided in the skiIIL-or if desired these plates I9 and 20 may be secured to the uppersurface of the ski I0. Where the plates I9 and 2G are mounted inrecesses provided in the ski Il they may be made relatively thick sothat the flanges I'l and I8 may engage the upper surface of the ski, orif desired additional channels may be provided for the anges il and i8.In Figure 1 the plates I9 and 29 rest upon the upper surface of the ski,and in Figures 2 and 3 these plates are placed in recesses. In Figure 1the depending flanges I'I and I8 have their ends flush With the surfaceof the ski, and in Figures 2 and 3 they enter into recesses.

The toe piece member I2 is constructed similar to the toe piece memberII, having an outer flange I4 and front and rear flanges I'I and I8',respectively, which extend downwardly of the bottom flange I3. Toothedor serrated locking plates I9 and 26' engage beneath the bottom plate I3and are secured to the ski I0 by means of screws 26 and 36',respectively, which pass through slots 23 and 35', respectively. Theunder side of the plate I3' is also provided with serrations or teethengaging with the serrations or teeth of the plates I9 and 20. l

The toe piece members II and I2 may be adjusted relative to each otherand to the ski I0, by loosening the screws 26 and 35 sumciently topermit the bottom plate I3 to be moved laterally of the ski II). Byreason of the pivotal mounting of the plate I3 locking plates I9 and 20,the adjustment of the plate I3 may be effected in such a manner that theouterupstanding flange I4 will contact with the side of the shoeirrespectively of the conguration of the shoe, the end flanges Il and I8 holding the plates I9 and 20 with their confronting edges inparallelism. When the angular position of the side flange I4 isdetermined, the plate I3 may be moved inwardly or outwardly of the skito the limit provided by the length of the slots 28 and 35 which are ofa length sufficient to admit of minimumY and maximum adjustment of theplate I3. After the plate I3 has been properly adjusted the screws 2Band 34 are tightened so that the plate I3 mll be held firmly in itsadjusted position with the serrations or teeth of the plate I3 engagingwith the serrations or teeth of the locking plates I9 and 20.

It will be apparent from the foregoing that an exceedingly simple andpractical toe piece has been provided which may be mounted on skiconstructions at present in use, and that when the toe piece has beenproperly adjusted it will not easily get out of adjustment, neither willany initial or subsequent adjustment of the toe piece injure or beaiected by the ski, as is the case where the teeth of the clampingdevices bite into the material of the ski.

Instead of the slots I5, clamping devices as shown in Figures 4 and 5can be substituted, which are adjustable to various depths of the solesof the shoes. The side plate II are provided with recesses 65, engagedby projections 66 on a guard 6l held to the side plates by a screwfastening device 68. The shoe of the user is provided with a metalplate, as is knowmand this is locked by the guard B'I when the guard isin proper positionA It is, of course, understood that various changesand modications may be made in the details of construction of the abovespecifically described embodiment of this invention Without departingfrom the spirit thereof, such changes and modications being limited onlyby the scope of the appended claims.
